OPERATING INSTRUCTIONS BEFORE USING THE MITER SAW WARNING: To avoid mistakes that could cause serious, permanent injury, do not plug the tool in until the following steps are completed: ● ● ● ● ● Completely assemble and adjust the saw, following the instructions (SEE ASSEMBLY AND ADJUSTMENTS SECTIONS). Learn the use and function of the ON/OFF switch, upper and lower blade guards, stop latch, bevel lock handle and cover plate screws.
KEEP YOUR WORK AREA CLEAN Cluttered areas and benches invite accidents. WARNING: To avoid burns or other fire damage, never use the miter saw near flammable liquids, vapors or gases. ● ● ● Plan ahead to protect your eyes, hands, face and ears. Read and understand the operator’s manual and labels affixed to the tool. Learn its application and limitations as well as the potential hazards specific to this tool.
Never cut freehand: ● Brace your workpiece firmly against the fence and table stop so it will not rock or twist during the cut. ● Make sure there is no debris between the workpiece and the table or fence. Make sure there are no gaps between the workpiece, fence and table that will let the workpiece shift after it is cut. ● Keep the cut piece free to move sideways after it is cut off. Otherwise, it could get wedged against the blade and thrown violently. ● Only the workpiece should be on the saw table.
BODY AND HAND POSITION (FIG. 26) WARNING Never place hands near the cutting area. Proper positioning of your body and hands when operating the miter saw will make cutting easier and safer. Keep children away. Keep all visitors at a safe distance from the miter saw. Make sure bystanders are clear of the saw and workpiece. Do not force the saw. It will do the job better and safer at its designed rate.
BASIC SAW OPERATIONS 27 1 TURNING THE LASER GUIDE ON (FIG. 27) Press the on/off rocker switch (1) to “ON” position to activate the laser guide. 4 TURNING THE SAW ON (FIG. 27) This miter saw is equipped with a two step ON/OFF trigger switch.

COMPOUND CUT (FIG. 31) A compound cut is the combination of a miter and a bevel cut simultaneously. ● Loosen the miter handle (1). Lift up the positive stop locking lever (2) and position the table at the desired angle. Release the positive stop locking lever (2) and lock the miter handle (1). ● Loosen the bevel lock handle (3) and position the cutting head at the desired bevel position. Lock the bevel lock handle (3).
CUTTING BOWED MATERIAL (FIG. 33) A bowed workpiece must be positioned against the fence and secured with a clamp (1) before cutting as shown. Do not position workpiece incorrectly or try to cut the workpiece without the support of the fence. This will cause the blade to bind and could result in personal injury. 33 CUTTING GROOVES (FIG. 34) WARNING: DO NOT USE A DADO BLADE, use only the standard saw blade for this operation.
AUXILIARY WOOD FENCE (FIG. 36) When making multiple or repetitive cuts that result in cut-off pieces of one inch or less, it is possible for the saw blade to catch the cut-off piece and throw it out of the saw or into the blade guard and housing, possibly causing damage or injury. To minimize this, an auxiliary wood fence can be mounted to your saw. Holes are provided in the saw fence to attach an auxiliary wood fence (this provides additional depth of cut).
CUTTING CROWN MOULDING (FIG. 38, 39) Your compound miter saw is suited for the difficult task of cutting crown moulding. To fit properly, crown moulding must be compoundmitered with extreme accuracy. The two surfaces on a piece of crown moulding that fit flat against the ceiling and wall are at angles that, when added together, equal exactly 90°.
